15 current for each mode is defined in hardware using two resistors
22 enf-gpios:
26 ent-gpios:
30 richtek,rfs-ohms:
34 resistors limits the maximum flash current. This must be set
35 for the property flash-max-microamp to work, the RFS resistor
39 richtek,rts-ohms:
43 resistors limits the maximum torch current. This must be set
44 for the property torch-max-microamp to work, the RTS resistor
54 flash-max-timeout-us: true
